Katy Perry: A newer, better Britney Spears: Katy Perry does not dabble in Bad Romance. She is not Hard. And no one tries to make her go to Rehab. Unlike her pop peers, the wide-eyed 25-year-old California Gurl is a Teenage Dream. She wakes up in Vegas. She kisses a girl, "just to try it." Wheeeeeee! After dominating the summer with not one but two unstoppable, earworm hits, her latest album is at the top of the Billboard chart, sitting daintily right above that crankypuss Eminem. A girl like that has a boatload of hate coming her way.
